Insulation materials used in buildings can keep warm and soundproof, improve the comfort of living, and help to save energy and reduce emissions. Don't underestimate the contribution of insulation materials to energy conservation and emission reduction. In the development goal of building energy conservation proposed by the “Eleventh Five-Year Planâ€, the contribution rate of building energy conservation should reach 20%, that is, save 120 million tons of standard coal – of course, this Everything needs to be built on the premise of being safe and reliable.
Insulation materials can be laid on the inner wall, but the actual application of the insulation effect is not ideal, so the current insulation materials are usually laid on the outer wall. At present, the commercial external wall insulation materials available on the market mainly include polystyrene board, extruded board and polyurethane foam. The first two materials were used earlier than polyurethane foam. Some buildings still use these materials. Compared with polystyrene board and extruded board, polyurethane foam has the advantages of good thermal insulation performance, good heat resistance, long service life, light weight, convenient transportation and construction, water resistance is also good, and the price is slightly higher. At present, polyurethane foam has gradually replaced them and become the first choice for exterior wall insulation materials.
As an organic thermal insulation material, polyurethane foam also avoids the shortcomings common to all organic thermal insulation materials: flammable, high temperature and fire resistance, and release a large amount of toxic and harmful smoke at high temperatures. At the same time, after the polyurethane foam is burned, the flame temperature is high and the smog is diffused, which increases the difficulty for firefighters to rescue and evacuate the site personnel.
In addition to these organic insulation materials, another type of inorganic insulation material can be used as the exterior wall insulation material. These materials are non-toxic, tasteless and harmless, have high ignition point, good fire resistance, no chemical reaction at high temperature, no toxic and harmful gases, and good environmental affinity. Unfortunately, these inorganic thermal insulation materials have various difficulties when used as external wall insulation. For example, thermal insulation mortar cannot be applied to high-rise buildings, and the thermal insulation effect is not satisfactory. The new calcium silicate inorganic thermal insulation material is used in the engineering field. Technically immature; poor water resistance is a common problem of various inorganic thermal insulation materials; the most important problem is that the cost of inorganic thermal insulation materials is too high, such as inorganic rock wool board is more than 6 times the price of polyurethane foam. The high cost limits the large-scale use of inorganic insulating materials with excellent performance and environmental protection to a certain extent. The phenolic foam materials with better fire resistance than polyurethane can only be used in high-grade public buildings such as the Bird's Nest and the Water Cube.

We are a manufacturer of automatic door openers that are designed to provide people convenience. Automatic Door Systems` drive to provide that level of service is but one of the reasons why automatic doors are becoming more and more popular. Our Automatic Sliding Door systems are modern, space-saving and elegant.
Automatic sliding doors have many basic functions some of which include: automatic mode with full opening width and/or reduced opening width, and exit only for traffic control. The opening of automatic doors can also be adjustable to make the opening width smaller or larger. Important safety functions such as safety sensors prevent the door from shutting if persons or objects are in the detection zone. If the door leaves are inhibited when closing, they are immediately re-opened or if the door leaves are hindered when opening, they are immediately stopped by a safety automatic reversing mechanism.
Our most popular sliding automatic door. Think of this as the go-to door for everyday automation needs. All components fully tested and pre-assembled at factory for fast, trouble-free installation.

You will find our automatic sliding doors throughout in a wide variety of locations, including: Hospitals, Airports, Retail centers, Pharmacies, Hotels, Grocery stores, Hardware stores, Sporting goods stores, and more.
Automatic Sliding Doors can either be a single door sliding in one direction or bi-parting doors where each door leaf slides in the opposite direction. They are often used in grocery stores, entrances to shopping malls, hospitals and other applications where you want to provide your customers a hands free, safe and easy access to your building.In addition, one of the biggest benefits of automatic doors is energy savings. Since these doors only open when someone comes in or out of your building, it prevents the loss of energy when a door may otherwise be left open for a long time.
The control device of sliding automatic door contains basic function and extensional function, automatic operation / hold-open/closed/half-open to meet customer needs. Electric sliding door controller has multiple interfaces for complete access control systems for keeping your life and property more safety. Such as: safety beam photocell, electric locks, sensor etc. Its drive devices adopts European technology to integrate motor with gear box, which offers strong driving and reliable operation and increased power output , it can adapt to a large door.
Providing strength, beauty, and technology all in one package, Hongfa's line of automatic sliding doors provides entrance solutions for practically any application. An exclusive feature is Hongfa's sound-dampening track reducing operational noise to a mere whisper and stops vibration resonance that can be transferred to the building structures.
